ISSN: 1432-0584Keywords: IL-4 ; MGF ; MPDs ; Colony assay ; CFU-GMSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The effect of interleukin-4 (IL-4) on peripheral blood (PB) granulocyte-macrophage (GM) progenitors was investigated in the presence and absence of other hematopoietic growth factors, especially the mast cell growth factor (MGF), in eight healthy controls and in 26 patients with myeloproliferative disorders (MPDs) using a clonogenic cell culture assay. In the controls IL-4 was effective alone, stimulating myeloid colony growth in 50%, while MGF had no effect as a single factor. When either IL-4 or MGF was added to the combination of IL-3, GM-CSF, G-CSF, and IL-6, a statistically significant increase in the colony number was observed. The most potent colony formation took place when all these GFs were combined. In the combinations, the effect of IL-4 was additive, while MGF worked synergistically. In the MPDs, IL-4 had no effect at all on the GM progenitors in the whole group of MPDs or on the different subgroups.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1432-0584Keywords: Key words C-kit ; MGF ; AML ; Spontaneous growthSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The effect of the mast cell growth factor (MGF), also known as stem cell factor, steel factor, and kit ligand, alone or in combination with other GFs on clonogenic blast cell growth in 23 patients with acute myeloblastic leukemia (AML) was investigated. MGF alone enhanced colony formation by about 35%, being clearly stimulatory (〉20% increase in colony numbers) in nine patients. The additive effect of MGF on colony growth was observed in combination with interleukin-3 (IL-3). Preincubation of the cells with MGF in suspension did not sensitize them to the effect of IL-3, granulocyte-macrophage colony-stimulating factor (GM-CSF), G-CSF, or IL-4 in a clonogenic cell culture assay. Although almost all the blast cell samples expressed the c-kit the receptor for MGF, at the mRNA and/or the protein level, the cells did not necessarily respond to exogenous MGF. On the other hand, blast cells were able to respond to exogenous MGF even when the cells themselves expressed MGF. Neither the expression of MGF nor the response of blast cells to exogenous MGF was related to the capability of the cells to form colonies spontaneously. In conclusion, MGF alone, but especially combined with IL-3, was a potent growth factor for clonogenic blast cells in AML. Autocrine production of MGF by AML blast cells analyzed at the mRNA level was not related to autonomous growth of the cells.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1432-119XSource: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary Carbonic anhydrase (CA III) and myoglobin contents from isolated human muscle fibers were quantified using a sensitive time-resolved fluoroimmunoassay. Human psoas muscle specimens were freeze-dried, and single fibers were dissected out and classified into type I, IIA and IIB by myosin ATPase staining. Fiber typing was further confirmed by SDS-PAGE. CA III and myoglobin were found in all fiber types. Type I fibers contained higher concentrations of CA III and myoglobin than type IIA and IIB fibers. The relative concentrations of CA III in type IIA and IIB fibers were respectively 24% and 10% of that in type I fibers. The relative concentrations of myoglobin in type IIA and IIB fibers were 60% and 28% of that in type I fibers. Anti-CA III immunoblotting results from fiber-specific pooled samples agreed well with quantitative measurements. The results indicate that CA III is a more specific marker than myoglobin for type I fibers.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-675XKeywords: Acute myeloblastic leukaemia ; all-trans retinoic acid ; apoptosis ; differentiationSource: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract The effect of all-trans retinoic acid (ATRA) on leukaemia cell differentiation, proliferation and induction of apoptosis was studied by using autonomously growing blast cells isolated from eight patients with acute myeloblastic leukaemia (AML) either at diagnosis ( n=4) or at relapse (n=4). No morphological or functional differentiation induced by ATRA was observed in any of the cases studied. In cell cultures, inhibition of leukaemia cell growth by ATRA was obvious, especially in the case of clonogenic cells, and it was both time- and concentration-dependent. Induction of apoptosis was more difficult to achieve. The cells retained over 90% viability in suspension when the ATRA exposure at any of the concentrations studied was 48 h or less. When the time of exposure to ATRA was longer than 48 h, the viability of the cells decreased in a concentration-dependent manner. Apoptosis was observed morphologically in each of the AML cases with 10-5 to 10-8 M ATRA, if the incubation time of cells in ATRA was 72 h. The percentage of apoptotic cells increased with increasing ATRA concentrations from 12± 9% of 10-8 M ATRA to 78±12% of 10-5 M ATRA. The DNA electrophoretic method was able to detect apoptosis in all the AML samples exposed to 10-7 and 10-6 ATRA for 48 h and occasionally in cases where lower concentrations and longer exposure time were used. In conclusion, the present study shows that it is possible to induce apoptotic leukaemia cell death in vitro with ATRA in AML, and this effect is dependent on both concentration and exposure time.Type of Medium: Electronic ResourceURL:
